Conversion of a digital signal to a voltage that is proportional to the input
value. See also A/D.
digital-to-analog
converter
A device that converts digital data into analog signals. See also ADC.
Digital Private-Line A type of digital communication that utilizes privacy call, as well as
memory channel and busy channel lock-out to enhance communication
efficiency.
digital signal
processor
A microcontroller specifically designed for performing the mathematics
involved in manipulating analog information, such as sound, that has
been converted into a digital form. DSP also implies the use of a data
compression technique.
digital signal
processor code
Object code executed by the Digital Signal Processor in an ASTRO
subscriber radio. The DSP is responsible for computation-intensive
tasks, such as decoding ASTRO signaling.
